【0002】 [0002]
このような形式の流量調整器は、時間単位毎に要求される通流量を激しい圧力変動においてもできるだけ一定に保てるようにするために、例えば水道管内で使用される。 This type of flow regulator, in order to be kept as constant as possible in highly pressure fluctuations the passing flow rate required per time unit, is used, for example, water pipe.
【0003】 [0003]
従来公知の流量調整器は調整器ケーシングの通流通路内に、弾性材料から成る環状の絞り体によって周面係合された、円錐形にテーパされた制御ピンを有している。 A conventional flow regulator regulator casing flowing passage was engaged circumferential surface engaged by an annular throttle member made of an elastic material and has a tapered control pin conically. 前記の環状の絞り体は、この絞り体自体とケーシングに固定された構成部材との間で制御ギャップを制限しており、この制御ギャップの通流横断面は、通流時に形成される差圧下で変形する絞り体に基づき可変である。 Aperture of the annular, this has limited the control gap between the throttle body itself and the component fixed to the casing, flow cross section of the control gap, the difference pressure formed at the time of flowing in a variable based on the throttle body to be deformed. この場合、制御ギャップを制限するケーシングに固定された構成部材の周面には、周方向で互いに間隔をおかれ且つ通流方向に向けられた調整切欠きが設けられている。 In this case, the peripheral surface of the fixed component on the casing to limit the control gap in the circumferential direction are provided adjusting notches oriented in and Tsuryu direction spaced from each other.
【0004】 [0004]
このように、調整切欠きが調整器ケーシングの内周面に設けられており、場合によっては中心の通流孔が存在している流量調整器は既に公知である。 Thus, adjustment notches regulator is provided on the inner peripheral surface of the casing, the flow regulator flowing hole in the center is present in some cases are already known. しかし、これらの従来公知の流量調整器は、時間単位毎に通流する液体量が完全に一定には保たれず、圧力の上昇に伴って僅かに増大するという欠点を有している。 However, these conventional flow controller has the disadvantage that the amount of liquid Tsuryu per time unit is not kept completely constant, slightly increases with increasing pressure.
【0005】 [0005]
調整切欠きを制御ピンの外周面に有する流量調整器も既に公知である(例えばドイツ連邦共和国特許出願公開第4041116号明細書参照)。 A flow regulator having-out adjustment notches on the outer peripheral surface of the control pin is also already known (see, for example, specification German Patent Publication No. 4,041,116). これらの公知の流量調整器は、要求された通流量を比較的低い液圧において達成するという点において優れてはいるが、圧力上昇時に再び減少する、通流目標値を著しく上回る通流最大値がしばしば生ぜしめられる。 These known flow regulator requested but is superior in terms of achieving a relatively low hydraulic pressure the passing flow rate, decreases again when the pressure increases, significantly above flowing target value flowing maximum There is often caused.
【0006】 [0006]
ドイツ連邦共和国特許出願公開第2131117号明細書に基づき既に公知の流量調整器の弾性的な絞り体は、水圧に関連して軸方向でも半径方向でも対応する調整面に対して押圧される。 Elastic diaphragm of already known flow regulator based on German Patent Application Publication No. 2131117 is pressed against the adjustment surface corresponding in radial direction in the axial direction in relation to the water pressure. 更に、この従来公知の流量調整器の弾性的な絞り体は成形された中心の制御ピンに周面係合している。 Further, elastic diaphragm of the conventional flow controller is engaged circumferential surface engaged with the control pin of the central molded. また更に、前記の弾性的な絞り体は若干の盆状の凹所を備えたショルダ面に載置されている。 Furthermore, elastic diaphragm of the rests on the shoulder surface having a slight basin-shaped recess. これらの盆状の凹所は、低い吸込圧力において付加的な液体量が調整器ケーシングの内周面に沿って弾性的な絞り体の下方を通流できるようにする。 These basin-shaped recess, so that the lower side of the elastic diaphragm body can flows along the inner peripheral surface of the additional amount of liquid is regulator casing at low suction pressure. 更に、前記ショルダ面に設けられた凹所は、弾性的な絞り体を未だ絞り作用を有さない状態で波状に成形された制御ピンに進入させる。 Furthermore, the recess provided on the shoulder surface, thereby entering the control pin molded into corrugated in a state that no still throttling the elastic diaphragm body. それというのも、差し当たっては弾性的な環の前後でその進入及び変形に必要とされる差圧を形成することができないからである。 Also since, in the meantime it is not possible to form a pressure difference required for the entry and variations before and after elastic ring. 吸込圧力の上昇に伴ってようやく環状の弾性的な絞り体はシール作用を以て埋まる程度にショルダ面の盆状の凹所に押し込まれ、これにより調整に必要な差圧を発生させることが可能である。 Finally annular resilient diaphragm member with increasing suction pressure is pressed into basin-shaped recess in the extent shoulder surface filled with a sealing action, it is possible to thereby generate a pressure difference necessary to adjust .
【0007】 [0007]
軸方向制御面及び半径方向制御面を時間的にずらして負荷することにより、従来公知の流量調整器を以て既に比較的低い予圧において要求された調整水量が得られる。 By loading the axial control surface and the radial control surface at different times, adjusting the amount of water that has already been requested in a relatively low preload with a conventional flow regulator is obtained. しかし、最大通流量は前記の従来公知の流量調整器でも、制御ピンと絞り体との間に残る制御ギャップの内法幅によって制限される。 However, maximum sheet flow in conventional flow regulator of the, is limited by the clear width of the control gap remains between the control pin and the diaphragm body.
最後に、米国特許第4000857号明細書に基づき公知の衛生組込み部材は、水道取付具の流出部開口部材に組込み可能である。 Finally, the known sanitary incorporated member based on U.S. Patent No. 4000857 can be incorporated into the outflow opening member of tap fittings. この従来公知の組込み部材は噴射調整器を有しており、この噴射調整器には冒頭で述べた形式の流量調整器に前置されている。 The conventional embedded member has an injection regulator is preceded in the form of a flow regulator mentioned at the outset in the injection adjuster. この流量調整器は弾性材料から成る環状の絞り体によって周面係合された制御ピンを有している。 The flow regulator has a control pin which is engaged circumferential surface engaged by an annular throttle member made of elastic material. 前記絞り体は、この絞り体自体と調整器ケーシングの内周面との間でも、絞り体自体と制御ピンの外周面との間でも制御ギャップを制限しており、この制御ギャップの通流横断面は、通流時に形成される差圧下で変形する絞り体に基づき可変である。 The throttle body, even between an inner peripheral surface of this diaphragm member itself regulator casing, which limits the control gap in between the outer peripheral surface of the aperture body itself control pin, flows across the gap control plane is variable based on the throttle body to be deformed by differential pressure formed during flowing. この場合、調整ケーシングの内周面にも、制御ピンの外周面にも、周方向で互いに間隔をおかれ且つ通流方向に向けられた、同一横断面形状の調整切欠きが設けられている。 In this case, the inner peripheral surface of the adjustment casing, also the outer peripheral surface of the control pin, directed to and Tsuryu direction spaced from each other in the circumferential direction, are provided adjustment notches of the same cross-sectional shape . 当該の従来公知の流量調整器も、異なる液圧下で時間単位毎に所望の通流量を、目標とする通流目標値に一定に保持することはできない。 Conventional flow regulator of the well, the desired through flow rate per time unit in different liquid pressure can not be kept constant in the flowing target value as a target.
【0008】 [0008]
従って本発明の課題は特に、冒頭で述べた形式の流量調整器を改良して、時間単位毎に所望される通流量を既に比較的低い液圧において達成し且つ液圧の上昇又は激しい変動に際しても事実上一定に保つ、比較的高い最大通流量を有する流量調整器を提供することである。 Therefore object of the present invention is especially to improve the form of the flow regulator mentioned at the outset, when accomplished by and fluid pressure increases or volatility in already relatively low hydraulic pressure the passing flow rate of the desired per time unit kept in substantially constant, it is to provide a flow regulator having a relatively high maximum sheet flow.
【0009】 [0009]
この課題を解決するために本発明では、絞り体の範囲内でそれぞれ異なって成形された横断面を有する調整切欠きが設けられており、比較的低い圧力域で遮断される調整切欠きが、比較的高い圧力域で遮断される調整切欠きに比べてより大きな、絞り体に面した内法開口幅を有しているようにした In the present invention in order to solve this problem, and adjusting notches provided outs having a cross section which is shaped different from each within the aperture body, adjustment notches are cut off at a relatively low pressure region outs, large more than the-out adjustment notches that are cut off at a relatively high pressure zone, and to have a clear width opening width facing the stop member.
【0010】 [0010]
本発明による流量調整器で 、環状の絞り体の圧力に関連した変形を片側に向かってだけでなく、内側に向かっても外側に向かっても作用させて、調整切欠きの適当な流れ横断面を制御することができる。 At a flow rate regulator according to the present invention, not only toward the deformation associated with the pressure of the annular aperture body to one side, even towards the inside to act outwardly, adjustment notches suitable flow cross it is possible to control the surface. 但し、本発明による流量調整器は絞り体の領域でそれぞれ異なって成形された横断面を有する調整切欠きを有している。 However, the flow regulator according to the present invention has an-out adjustment notches having a cross section which is shaped different from each in the region of the aperture body. この場合、比較的低い圧力範囲内で遮断される調整切欠きは、比較的高い 圧力範囲内で遮断される調整切欠きと比較してより大きな、絞り体に面した内法開口幅を有している。 In this case, the-out adjustment notches that are cut off in a relatively low pressure range, have a larger, inner size opening width facing the diaphragm body in comparison with-out adjustment notches that are cut off in a relatively high pressure range ing.
【0011】 [0011]
本発明によるこのような流量調整器は、低圧域を迅速に閉じる調整切欠きによって検出することができる一方で、絞り体が液圧によって既に極めて激しく負荷されて初めて、高圧域で遮断される調整切欠きが絞り体によって閉鎖されるという利点を提供する。 Such flow regulator according to the present invention, while it is possible to detect by-out rapidly closing adjustment notches a low pressure area, the diaphragm body is first already very severely loaded by a hydraulic, is blocked by the high-pressure zone adjustment It offers the advantage that cutout is closed by the diaphragm body.
【0012】 [0012]
この場合、本発明による流量調整器は、殊に高い最大通流量に対して小さな組込みサイズという点において優れている。 In this case, the flow regulator according to the present invention is excellent in that a small built size for particularly high maximum sheet flow. なぜならば、絞り体が同時且つ同期的に、両側に設けられた調整切欠きに向かって変形することができ、更に、絞り体の両側にそれぞれ調整されるべき平行な水流を有する制御ギャップが設けられているからである。 Because the throttle body is simultaneously and synchronously, can be deformed toward the-out adjustment notches provided on both sides, further control gap having parallel water flow to be adjusted on both sides of the diaphragm body is provided This is because are.
【0013】 [0013]
前掲のドイツ連邦共和国特許出願公開第2131117号明細書に基づき従来公知の流量調整器の中心の制御ピンには異なって成形された波状の加工成形部が設けられてはいるが、これらの波状の加工成形部は一般に均一な調整切欠きを制限しているに過ぎない。 While processing the molding portion of the corrugated molded differently to the control pin of the center of the conventional flow regulator based on a supra German Patent Application Publication No. 2131117 it is has provided, these wave Manufacturing process unit generally only have limited-out uniform adjustment notches. それぞれ異なって成形された調整切欠きは、当該のドイツ連邦共和国特許出願公開第2131117号明細書では設けられていない。 The-out adjustment notches that are shaped different from each, in the German Patent Application Publication No. 2131117 Pat not provided.

調整器ケーシング22の内周面にも、制御ピン又は制御円錐の外周面にも、絞り体の領域で異なって成形された横断面を有する調整切欠きがそれぞれ設けられていることが可能である Also the inner circumferential surface of the regulator housing 22, to the outer peripheral surface of the control pin or control cone,-out adjustment notches having a cross-section that is shaped differently in the region of the throttle body is a can are provided .
【0015】 [0015]
機能の分離及び最適化のために本発明の有利な構成では、調整器ケーシングの内周面に設けられた調整切欠きは、制御ピン又は制御円錐の外周面に設けられた調整切欠きに比べて異なって成形された横断面を有している。 In an advantageous embodiment of the present invention for the separation and optimization functions, regulator provided adjustment notches on the inner peripheral surface of the casing, compared with-out adjustment notches provided on the outer peripheral surface of the control pin or control cone and it has a cross section that is shaped differently Te.
【0016】 [0016]
この場合、比較的大きな内法開口幅を有する調整切欠きが調整器ケーシングの内周面又は制御ピンの外周面に設けられていると有利であってよい。 In this case, it may be advantageously provided in a relatively outer circumferential surface of the inner peripheral surface or the control pin of the adjusting notches regulator casing having a large clear width opening width.
【0017】 [0017]
比較的大きな内法開口幅を有する調整切欠きを、比較的低い圧力においてもゴム弾性的な絞り体によって良好に制御できるようにするためには、比較的大きな内法開口幅を有する調整切欠きがほぼ円セグメント形の横断面を有していると有利であってよい。 The-out adjustment notches having a relatively large inner size aperture width, in order to be able better controlled by a rubber elastic diaphragm body even at relatively low pressures,-out adjustment notches having a relatively large inner size aperture width there may be advantageously has a substantially circular segment-shaped cross section.
【0018】 [0018]
これに対して、特に流れ媒体の液圧が高い場合に遮断される調整切欠きは、これらの調整切欠きが比較的小さな内法開口幅を備えて、少なくとも1部分域が半円形及び/又はエッジを急峻に構成されているように設計されていてよい。 In contrast, especially-out adjustment notches that are cut off when the high hydraulic pressure of the flowing medium, provided with-out these adjustments notches relatively small clear width opening width, at least a portion region is semi-circular and / or it may be designed as being steeply constituting the edges.

以下に、本発明の実施例を図面につき詳しく説明する。 Hereinafter, an embodiment in detail per the present drawings.
【0022】 [0022]
図1及び図2には調整器ケーシング2を有する流量調整器1が示されている。 Flow regulator 1 with a regulator casing 2 are shown in FIGS. この流量調整器1の調整器ケーシング2は、一般に例えば衛生取付具の流出部開口部材(詳しくは図示せず)又はフレキシブルなホース導管の接続用取付具に挿入可能であり、これにより、時間単位毎に要求される水量を水供給導管内の圧力変動が激しい場合でも一定に保つことができる。 The regulator casing 2 flow regulator 1 is insertable into the generally example (not details shown) outflow opening member of the sanitary fitting or connection fitting flexible hose conduit, whereby the time unit the amount of water required for each can be kept constant even if the pressure fluctuations in the water supply conduit is intense.
【0023】 [0023]
流量調整器1は中心の制御ピン4を有しており、この制御ピン4は調整器ケーシング2の通流通路3内でケーシングに固定されて保持されている。 Flow controller 1 has a control pin 4 of the center, the control pin 4 is held fixed to the casing in the through flow path 3 of the regulator casing 2. 制御ピン4は弾性材料から成る環状の絞り体5によって周面係合される。 Control pin 4 is engaged circumferential surface engaged by the annular throttle body 5 made of an elastic material. 図2に示したように、制御ピン4は少なくとも前記絞り体5によって周面係合される長手方向延在部の部分域において、流れ方向Pf1とは逆向きでほぼ円錐形にテーパされている。 As shown in FIG. 2, in the part region of the longitudinally extending portion control pin 4 is to be engaged circumferential surface engaged by at least the throttle body 5, are tapered generally conical in the opposite direction to the flow direction Pf1 .
【0024】 [0024]
絞り体は、この絞り体自体と通流通路3を制限する調整器ケーシング2の内周面との間にも、絞り体自体と制御ピン4の外周面との間にも制御ギャップ6を形成しており、この制御ギャップ6の通流横断面は、通流時に形成される差圧下で変形する絞り体5によって可変である。 Throttle body, forms a control gap 6 in between to be, the outer peripheral surface of the aperture body itself control pin 4 between the inner circumferential surface of the regulator housing 2 to limit the throttle body itself and through passage 3 and is, flow cross section of the control gap 6 is variable by the throttle body 5 deforms differential pressure formed during flowing.
【0025】 [0025]
図1において認識されるように、調整器ケーシング2の内周面にも制御ピン4の外周面にも調整切欠き7,8が設けられており、これらの調整切欠き7,8は、それぞれ周方向で互いに間隔をあけられており且つ通流方向Pf1に向けられている。 As recognized in FIG. 1, the regulator adjustment notches 7,8 in the outer peripheral surface of the inner circumferential surface also controls the pin 4 of the casing 2 is provided with,-out these adjustments notches 7 and 8, respectively It is directed to and and Tsuryu direction Pf1 spaced apart from each other in the circumferential direction. 調整切欠き7,8は流出入方向で形成されており且つ制御ギャップ6に対して開いて形成されている。 Adjusting notches 7,8 are formed open to have and control gap 6 is formed in the inflow and outflow directions.
【0026】 [0026]
調整切欠き8が制御ピン4の外周面に比較的大きな内法開口幅を有しており且つ流れ媒体の低い圧力条件において既に遮断されるのに対して、調整器ケーシング2の内周面に位置する調整切欠き7は比較的小さな内法開口幅を有しているので、ゴム弾性的な絞り体は、この絞り体に作用する流れ媒体の圧力負荷が高い場合に初めて、調整器ケーシング2の内周面に設けられた調整溝又は調整切欠き7へ侵入することができる。 Against already blocked in relatively large clear width low pressure condition of which and flowing medium has an opening width on the outer peripheral surface of the adjusting notches 8 the control pin 4, on the inner circumferential surface of the regulator housing 2 since the adjustment notch 7 located has a relatively small inner size opening width, rubber-elastic diaphragm body, the first time when the pressure load of the flowing medium acting on the diaphragm body is high, the regulator casing 2 it can penetrate into the adjusting groove or adjusting notches 7 provided on the inner peripheral surface of the.
【0027】 [0027]
ゴム弾性的な絞り体5の、液圧に関連した多少なりとも著しい調整切欠き7,8への侵入によって、時間単位毎に流量調整器1を通流する水量が一定に保たれて、水圧が徐々に上昇した場合でも規定された時間単位毎の水量を上回る恐れはない。 Rubber elastic diaphragm body 5, by entering the more or less significant adjustment notches 7 and 8 associated with the hydraulic, water flowing through the flow regulator 1 per time unit is kept constant, the water pressure but there is no possibility that exceed the amount of water per unit of time, which is defined even if gradually increased.
【0028】 [0028]
比較的大きな内法開口幅を備えた調整切欠き8がほぼ円セグメント形の横断面を有しているのに対して、調整器ケーシング2の内周面に設けられた、比較的小さな内法開口幅を備えた調整切欠き7は、溝底部域がほぼ円セグメント形であり且つエッジの急峻な横断面を有している。 Whereas relatively large clear width-out adjustment notch with an opening width 8 has a substantially circular segment-shaped cross section, provided on the inner circumferential surface of the regulator housing 2, a relatively small inner dimensions adjusting notches 7 having an opening width has a steep cross-section of and edge is substantially circle segment-shaped groove bottom zone.
【0029】 [0029]
図3に示した線図から、流量調整器1は異なって成形された調整切欠き7,8によって調整される変形に基づき、低圧域でも高圧域でも極めて良好な一定の調整結果を得られるという点において優れているということが明らかになる。 From the diagram shown in FIG. 3, the flow regulator 1 is based on the deformation is adjusted by the adjustment notches 7,8 which are shaped differently, that obtained very good constant adjustment results in a high pressure zone at low pressure area It is apparent that is superior in point. 流量調整器1は、時間単位毎に所望される通流量を既に比較的低い液圧において達成し、この通流量を液圧の上昇又は激しい変動に際してもほぼ一定に保持する。 Flow regulator 1 is achieved already at relatively low liquid pressure the passing flow rate of the desired per time unit, to hold the passing flow rate substantially constant even when the fluid pressure increase or volatility. 図示の流量調整器の絞り体は同時且つ同期的に両側に設けられた調整切欠きに向かって変形可能であり且つ当該絞り体の両側にはそれぞれ調整されるべき平行な水流を有する制御ギャップが設けられているので、本発明による流量調整器は比較的高い最大通流量に対して小さな組込みサイズという点において優れている。 Throttle body shown in the flow regulator is controlled gap having simultaneously and synchronously deformable toward-out adjustment notches provided on both sides and parallel water flow to be adjusted respectively to either side of the aperture body since is provided, the flow regulator according to the present invention is excellent in that a small built-sized for relatively high maximum sheet flow.
